To all whom it may concern:

Be it known that we, J AMEs A. CAMERON and GUSTAF B. BIR both citizensof the United States, and residents of the borough of Brooklyn, in thecounty of Kings, city and'btate of New York, have invented certain newand useful Improvements in Machines for Making Surgeons? Bandages, ofwhich the following is aspecification.

.The present inventionrelates to devices for making surgeons bandages.

The main object of this invention is to reduce the number of operationsnecessary to produce bandages and to obtain as Wide a bandage aspossible from a given width of web. t

In carrying out this invention we employ a process whichconsists inslitting a Web of material lengthwise by severing it with an undulatingcut so as to simultaneously destroy the continuity of the Warp threadsadjacent to the cut and so as to leave a scalloped edge formed by weftthreads of unequal length, after which the material is rewound intocoils, preferably on a single shaft which when removed enablestheoperator to knock the coils apart,-thereby producing a plurality offinished bandages. The product thus formed is produced by a much smallernumber of operations and is of such a character that the edges thereofwill not unravel since the outermost warp threads, as described before,are destroyed in the process of slitting the ing warp threads are heldin place by the scalloped edge formed by the weft threads of unequallength.

'I he product obtained by this process may be characterized as asurgeons bandage which consists of a strip of material the be removedfrom the bandage before it is means for causing a blast of air toimrewound, by any suitable means, such as pinge upon the slittedsections.

In carrying out this process a machine 1s utilized which is providedwith a slitting means located in the path of the moving web for slittingthe web lengthwise before winding on undulat ng lines of severance,

fabric, and the remain-.

In the accompanying drawings the invention is disclosed in a concreteand preferred form from which, however, departure may be made withoutdeparting from the legitimate and intended scope of the invention asexpressed in the appended claims.

In the said drawings v F gure 1 is a vertical .cctional View through amachine which may be utilized iii connection with the process.

Fig. 2 is a detail sectional view of the slitting and rewinding meansand elements adj acent thereto.

Fig. 3 is an edge view of a portion of the tortuous rotary cutter.

Fig. 4 is a detail View looking in the direction of the arrow 4 of Fig.2.

Figs. 5 and 6 are sectional views showing stages of operation.

Fig. 7 is a general plan view of the device, on the line 'Z7 of Fig. 1,partly in section and broken away for the purpose of clearness ofillustration.

Fig. 8 is a detail view showipg a modification of the means for causinga blast of air to impinge upon the slitted material.

Fi 9 1s a view of a portion of the web with respect to the warp and weftthreads.

-Figs. .10 and 11 show the product obtained'by the process and by themachine, Fig. 10 being a view which shows the effect of the undulatingcut with the severed warp threads in position and with the scallopededge formed by the weft threads of unequallength, and Fig. 11 being aview similar to Fig. 10 but with the severed warp threads removed.

Similar characters of reference indicate corresponding parts in thedifferent views.

1, indicates a web of material from which the bandages are to be made,suitably supported on a roll in the machine, and 2 is the web guiderollers 3, 4 and 5.. 6 indicates the rewinding mechanism of a well-knownform which here consists of two surface rewinding which is led'therefromover suitable 2 g I if.

rolls 7 and 8 rotating in the same direction, and a pressure roll '9mounted to rise as the rollers 7, 8 and 9 and on which the slit sectionsare rewound. The cutting device here. consists of the rotary cuttingmember 12 which is provided with a tortuous cutting edge, as shown bestin Fig. 3. There may be a number of these rotary cutting members andthey are mounted in brackets 13 hung on the rails 1a in-a well-knownmanner, which rails are adapted to be raised or lowered so as to bringthe cutting member. 12 into engagement with the roll 8 by means of thecam 15 in a manner well understood in the art. The cam 15 also actuatesthe lever 16 pivoted at 17 and provided with a tension. roll18 whichserves to bring the'web of material into engagement with the rolls 7 or8 or both.

In the present embodiment of the invention one of the rewinding rolls 8constitutes the backing member for the cutting member 12. This backingmember is preferably provided with an inner core 19 and a plurality ofouter shells 20 of a material harder than the material ofwhich therotary cutting member 12 ismade, so that the cutting member willnot'cause indentations in the backing roll. The tortuous cutting edge ofthe rotary cutting member 12 is preferably blunt, that is to say, it 'isnot a sharp cutting edge since if it were it would be destroyed bycoming in contact with the'hard outer shells 20. The web of material isled over the guide rolls 3, 4 and 5 and over the tension roll 18 and inbetween the backing roll 8 and the rotary cutting member- 12, which byits action slits the web longitudinally on undulating lines, asindicated by X in Fig. 9. It will be noted. that this undulating cutwill sever a number of the warp threads X adjacent to the lines ofcutting, the remains of which may be seen at Y in Fig. 10. And at thesame time the undulating cut will. sever the weft threads X in such amanner as to leave a scalloped edge formed by weft threads of unequallength recurring at regular intervals, as

shown at Y in Figs. 10 and 11. The material may then pass around theroller 8 and to the rewinding shaft which rewinds the slitted sectionsside by side into a plurality of coils. When a sufficient diameter ofmaterial has been rewound the ,shaft 11 is re- "moved from the machineand the coils re.-

moved therefrom. If desired the web may be led over the hollow guideroller 21, which is interposed the line of travel between the slittingmeans and therewinding means and which is open 'to the atmosphere, asshown at 22. From thence the web may passback to the upper portion oftheroller 8 and then v .understood that when the coil has reached,

' more particularly in .Fi

the rewinding shaft 11. Thisihollow guide roll 21 is in communication,by means of suitable-piping at 23, with the containers or v tanks 24,and an air nozzle 25 of suitable con struction isarranged adjacent tothe open portion of. the hollow guide'roller 21 so that as the webtravels over the said guide roller 21 the air Will blow the severed warpthreads into the interior of the said roll 21 and thence into thetanksj24. The tanks 24 may be provided with suitable screening means forretaining the particles of the warp threads and for permitting theescape of the air in a well-known manner.

In order to facilitate the removal of the coils when the requisitediameter has been reached and to quickly sever the slitted sectionstransversely from the web, and for substituting a new rewinding shaft,we provide a bracket 26 at ,a point in advance of the rewinding means,which bracket is adapted to receive rewinding shaft 11 containing therewound slitted sections integral with the web of material. To make thisplain it will be say the diameter shown in Fig. 5, it may then beremoved and placed in the bracket 26, as shown .in Fig. 6. A secondrewinding shaft 11 is then inserted in the rewinding means to maintainthe slitted sections of the web in threaded relation to the rewindingmeans so that when the web is severed transversely between the tworewinding shafts the renewed operation'of the machine will continue therewinding of the material on the new shaft 11". and will thus obviatethe necessity' of the slow and careful threading of the web into the newshaft and into the new rewinding mechanism.

Preferably there is provided in connection with the bracket 26 two rowsof pins 27 spaced apart and which may be in the form of the well-knowncombs, as. shown g. 4:. These pins are interposed between the bracket 26and the rewinding means and when' the shaft 11 is-- removed from therewinding means and placed in the bracket 26, these pins 27 will piercethe material, as shown in Fig. 6, and will thus form a line transverselyof the web which Wlll render the severance of the web along a definiteline easy of accomplishment. The slitted sections may now be severedfrom the web by running a. knife across the said web between the tworows of transversely extending pins 27, the result of which is shown inFig. 2, when power mayagain be applied to the machine and the rewindingbe continued on the shaft 11*. In order to facilitate--the removal ofthat portion of the slitted section which is in tegral with the webafter it has been severed there is provided a. transversely extendingbar 28 adjacent to one of the rows of pins masses and ma be providedwith a handle 30 for manipu ation so that by the simple process ofdepressing the handle 30 the integral sections of the web may be uicklydisengaged after the web has een severed tiransversely. This is plainlyillustrated in In Fig. 8 is shown a slight modification of the devicefor removing the severed warp threads, which modification consistsmerely in providing the nozzle 25 with a plurality of openings 31opposite to slits in web instead of with a continuous slot 32, as shownI in Fig. 7.

The rewinding shafts 11 and 11, or as many others as may be desired, areadapted to engage in the guides 10 so as to rise with an increase in therewound material. This is more particularly illustrated in Fig. 7.
